Sweet! I'm about to build one of these for my first-time burn experience this year, to keep my hexayurt cool. Could I combine the solar panel you're using with a deep-cycle battery? I.e. have the solar panel replenish the battery whenever there's enough sunlight, to stretch the battery out for the whole week? (I have almost zero electrical knowledge, btw.)

Would I be able to recharge the battery with a solar panel?From what I have read in the multiple threads and over searches, I should be able to run the fan and pump on the battery for a week. CanI recharge my battery by disconnecting it from the fan and pump and connecting it to a 30 watt or 50 watt solar panel?I am weary of depending only on the panel should the weather be cloudy or dusty.
